To alt whom t may concern:

Be it known that I, Wam'nn EDWIN Par- 'riNciLIa a citizen of the United States, residing at East Providence, in the count of Providence and State of Rhode Islan have invented certain new and useful Improvements in Jordan Engines, of which the following is a specification.

My present invention ertains to Jordan engines which, as is wel known to those skilled in the art, are commonly employed for refining paper, rag or other stock prior to the passage of the stock to the screens.

Heretofore, 4so far as I am aware, the

material to be treated has been fed to the engine at the smaller or head end thereof, the feed opening being arranged radially and directly adjacent such small or head end. Under this arrangement the stock feeds endwise under pressure of the head of the stock in between the knives or blades on the plug and the shell. As Aa consequence, as the blades wear down and the plug is moved in endwise to compensate for such wear, the size of the openings between the blades becomes smaller and the degree of feed is proportionally reduced. With a view of increasing the feed capacity I heretofore moved the feed opening longitudinelly of the shell at some distance from the head end of the machine. but still retainfn or maintaining the radial arrangement o the intake pipe or feed channel Such ar rangement was found in actual practice to be defective as it was impossible to get the stock into the jordan. 'Ihe stock seemed to plug up in the opening. 'Ihe thick stock apparently acted as a filter, gradually re, ducin the flow of water owing to an accumu ation of fine stuff by the coarser until finally all inflow of water and stock ceased.

After the failure of such arrangement I conceived of the present invention which broadly stated, consists in arranging the feed opening or pipe at a tangent to the circumference of the plug, whereby unlooked for increase in capacity, with a marked conservation in power, was obtained. Furthermore, under the new arrangement, a longer time interval between necessary replacement of the bars or knives likewise obtains.

A Jordan engine embodying my invention is illustrated in the annexed drawings, where1n,

Fig. l is a side elevation of the improved en me; and i 1g. 2 a transverse vertical sectional view on the line II-II of Fig. 1, with parts broken away. In said li res, 1 denotes the shell' or casing of stan ard outline, exce t for the feed 1n et, said shell being provided with the usual removable heads 2 and 3, in which latter is provided the discharge 4. Said outlet may be adjusted about the head 3 to effect the discharge from the engine at the desired level.

'The cone or plug 5 is of standard form having spaced ars or blades 6 extendin longitudinally thereof. rIhe cone is secured to a shaft 7 mounted in suitable bearings so constructed as to admit of ylongitudinal adjustment of the cone or plug within the shell to compensate for wearing down of the bars. The shell liner is denoted by 8, and the bars or knives carried there by 9. The feed inlet or delivery channel, which may be round, square, or, in fact, any desired shape, is denoted by 10, and the liner' 1s cut away beneath the inner end thereof, the liner bars or knives also bein omitted at such point or space. As wil be seen the inlet is arranged tangentially of the cone and :shell and by preference the inlet, instead of opening into the neck of the shell as is usually the case, it is placed further along on the shell.

This arrangement of the feed adords an increased size of opening by introducing the stock upon an are to one side of the highest point or top of the cone so that the material is fed to and rests upon that portion of the cone which throughout the extent of the opening is travelling downward and away from the opening. Thus, the momentum ofthe stock is in no wise retarded, as it iswhen the opening is arranged radiall or at right angles, but is caught by the ives on t e downgoing side of the revolving cone and dragged down into the machine.

The gradually narrowin opening or the substantially V or wedge aped feed channel as it may be termed, with the rotating cone face with its bars forming the bottom handling in the usual screens and in the re of such channel, vserves to feed the stock into the machine at a rapid rate. As a con sequence the material passes through the jordan at an increased speed. This method of introducing the Stock has been foundV to double the capacity of a jordan. Where heretofore with the usual equipment I have been able to handle less than tons in 24 hours. I am able with the same equipment modified so as to introduce the4 material tangentially to handle over 80 tons in the same time interval with a material saving in power.

Moreover, repairs are much less per ton of stock used. One reason for this is that I am enabled to use the plug longer t-han I fcould with the old feed entrance, and this Without material] reducing the capacity of the ma. chine. he wearing down of the knives or bars does not seriously affect the capacity so long as there is any bucket left between the knives.

Again the jordan, with my invention applied thereto, will take and handle a relative rough and half-beaten stock; as a consequence it is not as necessary to reduce the stock in the beaters so far as under the old conditions.

The machine produces a free working stock, but refines the same sufficiently for mainder of the process to which the screened stock is subjected.

What is claimed is:

1. In a Jordan engine, the combination of a shell; a plug mounted for rotation therein;

plug.

a series of bars or knives carried by each of said members; and means for introducing stock directly on the bars of the plug on the downgoing `-side thereof and likewise against the adjacent portion of the shell and the bars carried thereby.

2. In a Jordan engine, the combination of a shell having bars or knives arranged interiorly thereof; a plug mounted for rotation therein; bars or knives arranged exteriorly thereof; and a feed inlet for the stock to be treated arranged tangentially of the plug, the inlet opening directly onto the knives of the cone and the co-acting adjacent face of the shell.

3. In a Jordan engine, the combination of a shell having bars or knives arranged interiorly thereof; a plug mounted for rotation therein; bars or knives arranged exteriorly thereof; and a Wedge shaped inlet for the stock formed between the wall of the shell and the down-going side of the plug.

4. In a Jordan engine, the combination of a shell having a neck portion; a feed opening arranged tangentially thereof and at a point removed from the neck, said opening discharging directly onto the adjacent wall of the shell; knives located interiorly of the shell except at that portion where the feed opening` is located; a plug mounted for rotation in the shell; and knives carried by the In testimony whereof I- have signed my name to this specification.
